Just a follow-up. There was several things wrong with the differential. The looseness in the rear axle is due to worn axle splines. The noise that you hear when I rotate the tires is a busted bearing inside the trans. I ended up pulling out the transmission and replacing several of the bearings. There is actually a hole in the side of the diff that was caused by the busted bearing.
Johnny Williams I still have the play in the axles. It is because of the worn splines. Leaking fluid is because of worn seals. Seals can be easily changed w/o removing trans. If the bearings are shot trans has to come out. Not really that hard to take out.

I didn't have to replace the axles or the socket that they fit into inside the transmission. Most of the play is from worn splines on the axles. The Ranger has about 6,000 miles on it, so I guess that is considered "normal" for that many miles. I did replace the seals that are here though. Notice all the grease/grime around the axles. The noise that I had was from a busted bearing on the reverse shaft. When the bearing went, it also broke out a huge hole in the side of the case. Had to weld up and re-machine the case for the new bearing. I think the bearing failed because the previous owner used 80-90W gear oil in the transmission. The oil is so thick, it could not reach the bearing.
On my 570 the right axle has come out of the differential so you can see the spline on the shaft?

I have the same thing going on. Was it difficult to change?

We just returned from a ride and your video looks just like my Ranger rear diff...not looking forward to the repair. Thanks for sharing!
I may look you up for some guidance if you don't mind.

Was that considered normal play, or did you have to rebuild differential?

Could scheduled fluid changes have prevented this?
